To rtZZ whom it may concern:

Be it known that 1, CHARLES T. ROGERS, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in a Combined Vacuum-Pan and Condenser; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in combined vacuum-pans and condensers; and the object of my improvement is to provide a simple and economical device of this type, one in which the condenser is located inside of the vacuum-pan instead of being separate from it, as usual, and one in which the amount of condensing fluid supplied to the condenser may be regulated to a nicety.

With these objects in view my invention consists in the construction and combination of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation, partly in section, of my combined vacuum-pan and condenser; and Fig. 2 is a top view of the same, partly in section.

(0 represents the vacuum-pan, which is of the usual construction. The top of this pan is closed by a plate 7), which is provided with a number of vertically-arranged perforations 0. These perforations are preferably arranged in a circle upon the plate 6. Above the plate I) is a curved casing 0 the space between the plate Z) and the casing 03 serving as a reservoir for the condensing liquid.

f indicates the supply-pipe'for the condensing liquid. The pipe f, casing d, plate I), and the top of the pan a are fastened together in any desired manner, preferably by means of bolts and packing. The plate 5 is cut away just above the perforations c, forming a circular groove or channel, and in this groove or channel is located another plate 9, provided with perforations h, which when the plate 9 is in position register with the perforations c. The plate g is adjustable upon the plate 6 by means of the screws 7; and j, operated by the hand-wheels s t. The screw z'passe's through a-lug l0, fastened to the top of the pan and engages a projection l on theplate g. The screw j is similarly mounted. It is obvious by moving the plate g back and forth above the plate 6 that flow of condensing liquid through the perforations h and 0 may be regulated exactly as desired or may be entirely out off.

Below the plate b is located the receptacle m for the condensed fluid. This is preferably made out of two parallel sheets of metal separated by heat-insulating material a for the purpose of preventing surface condensation on the outside of the receptacle m. Any suitable non-conductor of heat may be usedsuch, for example, as asbestos or mineral wool. This receptacle terminates in a sloping discharge-neck 0, which is connected to the vacuum-pump and passes through the wall of the pan 0. One or more braces 9, fastened to the receptacle and to the interior of the vacuumpan, serve to hold the receptacle in its proper position. A curved deflecting-plate q is used near the top of the pan to prevent the condensing fluid from running around the interior of the pan a, and this plate compels all the condensing fluid to drop directly into the receptacle m.

By means of the perforated plates 5 and g the amount of condensing fluid delivered into the interior of the vacuum-pan can be regulated exactly without changing the number of streams or jets and without varying the main supply, thus rendering it possible to obtain eflicient condensation with a less amount of stood, therefore, that I do not limit myself to the exact details shown and described.

The vacuum-pan a is supported by means of standards 3, engaging with projections 4 on the base ofv said pan. Any desired number of these standards maybe used.

a, o, w, w, y, .2, 1, and 2 represent inlet and outlet pipes for the admission and drawing off of the liquid to be evaporated, the evaporated liquid, and the heating mediumsuch as steam, for example.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination ofavacuum-pan, a condenser located Within said pan, means for su p.- plying jets of condensing fluid to said condenser, and means for varying the size of said jets, substantially as described.

2. The combination of avacuum-pan, a perforated plate applied thereto, a second perforated plate looated in proximity to said firstnamed plate, and means for moving one of said plates relatively to the other to vary the supply of fluid delivered through said plates, substantially as described.

3. The combination of a vacuum-pan, a per forated plate applied to the top thereof, a revoluble circular plate located above said firstnamed plate, and means for moving one of said plates relatively to the other, substantially as described.

4. The combination of avacuum-pan, aplate closing the top of said pan and provided With a circular perforated trough, a movable circular perforated plate mounted in said trough, and means for moving said second -named plate, substantially as described. 1

5. The combination of a vacuum-pan, a plate closing the top thereof, said plate being provided with a circular perforated trough, a movable perforated circular plate mounted in said trough, means for moving said last-named plate, a casing located above said plates, and an inlet-pipe passing through said casing, substantially as described.

6. The combination of a vacuum-pan, aplate j closing the top thereof, said plate being provided'with a circular perforated trough, a

movable circular perforated plate mounted in said trough, and adjusting-screws for moving said second-named plate, substantially as described.

7. The combination ofa vacuum-pan, a perforated plate closing the top of said pan, a second movable perforated plate located in proximity to said first-named plate, means for moving said second-named plate, and a condenser located in said pan underneath said plates, substantially as described.

8. A condenserhavin g an open top and a'discharge-opening, said condenser being made of parallel sheets of metal separated by anonheat-conducting material, substantially as described.

9. The combination of a vacuum-pan, a plate closing the top thereof, said plate being provided with a circular perforated trough, a movable circular perforated plate located in said trough, means for moving said secondnamed plate, a casing located above said plates, an inlet-pipe delivering into said casing, and a condenser located beneath said plates and having a discharge-neck passing out through the side of said pan, substantially as described.

In testimony whereof I alfix my signature in presence of two Witnesses.

CHARLES T. ROGERS.
